Other fibres are those non-asbestos fibres that are used in construction and manufacturing, often as asbestos-replacement materials in insulation products.
Refractory ceramic fibres (RCF) are considered to be carcinogenic, and have been used as an asbestos replacement material, particularly as insulation to ductwork, fire compartmentation and very high temperature applications such as kilns and furnaces.
Machine (or man) made mineral fibres (MMMF) and aramid fibres have also been used in insulation and fire protection.
Yes. So if these are being installed, replaced or maintained they must be subject to a COSHH assessment and the exposure to these fibres controlled. These fibres have Workplace Exposure Limits (WELs), both as gravimetric (mg/m³) or as a fibre count, in fibres / cm³.
